“…This research found that both chlorine-based compositions can effectively reduce the number of planktonic cells and biofilms of Salmonella enteritidis on food contact surfaces. In addition, some studies examined the effectiveness of alcohol-based disinfectants, namely ethanol with a mixture of chlorine and lactic acid, against several Salmonella serotypes on stainless steel surfaces conducted by Zhang [6]. Based on the observations, it was concluded that the ethanol-based disinfectant mixture was effective in reducing the presence of Salmonella on stainless steel surfaces.…”

Salmonellosis is one of the most common foodborne infections worldwide. Various Salmonella enterica serotypes can cause this infection and can be transmitted through food contact surfaces. The most common way to prevent this infection is by applying disinfectant on food contact surfaces. Therefore, this research aims to summarize the effect of different disinfectants for controlling Salmonella serotypes on food contact surfaces. PRISMA guidelines were used as the method to find suitable sources for this systematic review. Relevant studies that were used are retrieved from several databases such as Science Direct, EBSCOhost, Taylor & Francis, SAGE, and Scopus. The keywords used to identify the relevant studies were “disinfectant”, “Salmonella sp.”, “food contact surface”, “food safety”, and “hygiene”. The initial search in the databases yielded 75 articles. After the screening process based on the criteria of the article, only 6 articles were used in the final systematic review. The result showed that the effect of disinfectants on foodborne pathogens, especially Salmonella serotypes, can be influenced by the composition of the disinfectant, the type of serotype, and the food contact surface material used. Therefore, in-depth consideration is needed regarding the factors that influence the effectiveness of a disinfectant, especially on food contact surfaces in the food industry.

“…Bacterial cells in biofilm show higher antibiotic resistance and survive longer than planktonic cells (Wijman, Leeuw, Moezelaar, Zwietering, & Abee, ). Once biofilms are formed, bacteria are difficult to remove completely (Zhang, Ye, Juneja, & Xu, ). Hence, the contamination and antibiotic resistance of B. subtilis on food contact surfaces and food‐processing equipment increase due to their biofilm‐forming capacity.…”

Bacillus subtilis shows high contamination and antibiotic resistance in the food industry due to their biofilm‐forming capacity. This study aimed to search a biopreservative to inhibit the biofilm formation of B. subtilis. The effect of garlic extracts, nisin, ε‐polylysine, and citric acid on bacterial growth, cell surface hydrophobicity, and cell morphology were observed to provide insight into the antibiofilm mechanisms. Results showed that nisin, ε‐polylysine, and citric acid completely inhibited the growth and biofilm formation of B. subtilis at 0.15, 0.09, and 1.5 mg/ml, respectively. Garlic extracts inhibited cell elongation, but cannot completely inhibit the biofilm formation even at 1.8 mg/ml. The antibiofilm activities of four biopreservatives were due to antibacterial activities, reduction in extracellular polymeric substances production, and cell surface hydrophobicity. Among these four biopreservatives, ε‐polylysine, which caused cell to collapse, had the highest antibacterial and antibiofilm activities followed by nisin, citric acid, and garlic extracts. Practical applications Bacillus subtilis shows high contamination and antibiotic resistance due to their biofilm‐forming capacity. Finding a biopreservative to inhibit the growth and biofilm formation of B. subtilis was important in food industry. This study could pave the way for controlling B. subtilis in planktonic and biofilm states.

“…Also, RSM was used to investigate the influence of the concentration of sodium chloride, calcium chloride, and urea in reducing biofilm formation by B. cereus (Ranmadugala et al, 2017). A predictive model for estimating the removal of Salmonella biofilm in SS coupons was obtained using various concentrations of chlorine (50-150 ppm), ethanol (10-30%), and lactic acid (1-3%) (Zhang et al, 2017). RSM was also used to build a model to predict reductions in uropathogenic Escherichia coli biofilms using the combination of cranberry extract (3-9%), caprylic acid (0.01-0.05%) and thymol (0.01-0.5%) (Kim & Rhee, 2018).…”

“…Response surface methodology (RSM) is recognized as a powerful gathering tool of mathematical and statistical approaches which are helpful to analyze and model problems, where a response of interest is affected by multiple independent variables for response optimization (Montgomery, 2005;Chelladurai et al, 2021). The RSM has been used as a mathematical strategy to predict the inactivation of monospecies biofilm from different microorganisms (Kim & Rhee, 2018;Ranmadugala, Ebrahimnezhad, Manley-Harris, Ghasemi, & Berenjian, 2017;Zhang, Ye, Juneja, & Xu, 2017). Nevertheless, to our knowledge, no study has modeled the removal of multispecies biofilm, especially using the RSM.…”

O leite cru apresenta uma microbiota diversificada capaz de formar biofilmes em diferentes superfícies da indústria de laticínios. Devido a essa ampla diversidade, as comunidades dos biofilmes associadas às superfícies industriais são geralmente complexas e constituídas por diferentes espécies. A fim de se obter produtos seguros e de qualidade, a prevenção da formação e a remoção dos biofilmes, bem como a inibição de suas células são necessárias em razão dos muitos problemas causados nas indústrias, como bioincrustação, corrosão, resistência microbiana aumentada a agentes sanitizantes e contaminação dos alimentos. A caracterização da microbiota formadora de biofilme multiespécie pode contribuir para o desenvolvimento de estratégias de controle e, ou eliminação dos biofilmes no setor industrial onde estas estruturas são consideradas problemas. Assim, este trabalho teve como objetivo avaliar a influência das moléculas nisina e furanonas sobre a formação de biofilme multiespécie pela microbiota do leite cru refrigerado. Foi feito também o isolamento e identificação de bactérias desses biofilmes e avaliada a capacidade de formação de biofilme monoespécie de isolados selecionados. A resistência do biofilme multiespécie formado por quatro isolados ao sanitizante ácido peracético foi avaliada usando a metodologia de superfície de resposta (MSR). Após incubação por 10 dias a 4 ºC, o número de células sésseis no cupom de aço inoxidável mantido imerso em leite cru variou de 5,5 a 6,2 log UFC/cm2 de psicrotróficos. A adição de nisina ou furanonas ao leite não influenciou no número de células viáveis no biofilme, mas alterou a diversidade microbiana. Os principais gêneros encontrados nos biofilmes foram Acinetobacter, Serratia, Lactococcus, Pseudomonas e Bacillus, os quais são contaminantes de grande importância para a indústria de laticínios. A partir dos biofilmes multiespécies, foram obtidos 36 isolados e identificados pelo sequenciamento do gene 16S rRNA. Dentre os isolados, 69,5% (n=25) foram capazes de formar biofilme monoespécie, sendo classificados como formadores de biofilme fracos a fortes. Rahnella inusitata F083, Lactococcus garvieae C081 e Lactococcus laudensis F103 foram os que apresentaram o maior capacidade de produção de biofilme. A atividade proteolítica foi detectada em 63,8% (n=23) dos isolados e as moléculas sinalizadoras acil homoserina lactonas (AHLs) de cadeia curta a média (C4-C8) foram detectadas em cinco isolados identificados como R. inusitata. Para a formação de um biofilme multiespécie, quatro isolados que apresentaram capacidade moderada a forte de formação de biofilme, identificados como Pseudomonas fluorescens, R. inusitata, Staphylococcus aureus e Micrococcus aloeverae foram utilizados. Após 10 dias de incubação a 4 ºC, o biofilme multiespécie atingiu em torno de 108 UFC/cm2. A otimização das condições de inativação de células desse biofilme por MSR consistiu na avaliação de diferentes concentrações de ácido peracético (0,05-0,5%), tempos de tratamento (5-30 min) e temperaturas (25-60 ºC) como variáveis independentes. As três variáveis independentes apresentaram efeito positivo na inativação das células dos biofilmes e a inativação máxima de, aproximadamente, 6,0 ciclos log UFC/cm2, foi obtida quando os três fatores foram utilizados nos maiores valores. As evidências da complexidade dos biofilmes multiespécies formados em superfícies comumente utilizadas nas indústrias de laticínios reforçam a necessidade de compreender essa microbiota, as possíveis alterações em sua composição e resistência a tratamentos com sanitizantes, a fim de melhorar as estratégias de inativação desses biofilmes nas indústrias. Palavras-chave: Biofilme multiespécie. Diversidade microbiana. Nisina. Furanona. Resistência a sanitizantes.
